Individually mouth-blown by expert artisans, these double insulated glasses are made from two layers of heat-resistant borosilicate glass, which keeps hot and cold drinks at their ideal temperature for longer. A clever silicone vent on the base regulates the external wall of the glass, which prevents messy condensation and means you can hold a glass of hot liquid without burning your fingers. Lightweight to hold and easy to clean.
Borosilicate glass.Wash in warm, soapy water before first use and dry thoroughly. For all subsequent uses, wash and dry by hand or pop in the dishwasher.
